Okay so because it's 10% off you're going to take the original price ($25) and move the decimal over once. So, $2.50. Now back to the original price!
$25.00 - $2.50 = $23.50 for the sweatshirt. I don't think I explained that very well, but that'd be how you found your answer?
F(1)=8000x0.55x1=4400
f(2)=8000x0.55x2=8800
(8800-4400)/2=2200
Answer:
Step-by-step explanation:Step 1: Use quadratic formula with a=1, b=-2, c=-2.
x=
−b±√b2−4ac
2a
x=
−(−2)±√(−2)2−4(1)(−2)
2(1)
x=
2±√12
2
x=1+√3 or x=1−√3
Answer:
x=1+√3 or x=1−√3
Ummm The is no pattern to the data
Answer:
x = -3, 7
Step-by-step explanation:
x² - 4x - 21 = 0
factor (what multiplies to -21 and adds to -4?):
3 and -7
(x + 3)(x - 7) = 0
zero product property:
x = -3, 7
